Definitions

  • THIS INVENTION relates to heat transfer systems wherein a continuous web of material is to be transported across the surface of one or more hot plates whereby the web is subjected to an elevated temperature for a predetermined period.
  • the invention is concerned with corrugating machinery in which so-called single faced board with glue applied to the exposed tips of a corrugated sheet is brought together with a liner which is thus bonded to the glued tips to form a double faced board, and the composite board is carried beneath a conveying belt past a bank of heaters which assist in the bonding of the liner to the corrugated tips of the single faced board.
  • a system of this kind incorporates a series of weight rolls which bear on the conveying belt to maintain contact between the board and the hot plate surfaces of the heaters, in order to ensure adequate heat transfer.
  • An object of the present invention is to provide a heat transfer system wherein the aforementioned disadvantage is at least substantially avoided.
  • a heat transfer system in which a continuous web of material is carried past a series of hot plates, there being means imposing a load on the face of the material remote from the hot plates to maintain contact between the material and the hot plates; characterised in that said load applying means includes at least one flexible vessel containing a fluid medium and adapted to press said material against the hot plates thereby to conform to the surface of the latter irrespective of any undulation thereof.
  • a single faced corrugated board 10 with glue applied to the tips of the corrugations is brought together, beneath a roller 11, with a continuous liner sheet 12.
  • the double faced board so formed then travels in the direction of arrow 13 across a number of steam chests 14 providing a continuous upper hot plate surface 15.
  • a series of weight rollers 17 bear against the upper surface of belt 16 as it passes over the hot plate surfaces 15 to maintain contact between the latter and the liner 12.
  • the present invention is based upon an appreciation of the need to permit the board to follow any distortion or undulation of the hot plate surface, thus ensuring uniform contact and heat transfer across the entire width of the board.
  • the weight rollers 17 are replaced by a series of flexible vessels or bags 20 which are at least partially filled with water.
  • Each vessel 20 bears upon a thin steel plate 21, of between 1.5 mm and 2 mm in thickness, which is loosely pivotable about a transverse rod 22 at its upstream end in relation to the direction of travel of the board.
  • the vessels 20 may be made from natural or artificial rubber or a flexible plastics material, and each is preferably provided with filling and drainage means for topping up or for controlling the volume of water contained in them and thus the weight applied by them.
  • the board 10, 11 is maintained in contact with the hot plate surfaces 15 irrespective of any undulation or distortion thereof. Therefor, efficient heat transfer is ensured and there is substantially uniform pressure applied right across the board thus avoiding crushing of the side regions thereof.
  • Other advantages include reduced maintenance, even pressure applied to the hot plates, and the achievement of higher machine speeds owing to the complete heat transfer afforded.
  • the weight may be adjusted by an operator, according to the conditions prevailing.
  • the liquid contained within the vessels 20 may be other than water, and the attitude and arrangement of the various parts may be other than as a flat bed process as illustrated. Clearly if the board is to travel vertically instead of horizontally then some means will be required to apply a load to the back of the vessels 20 to urge them towards the belt 16.
  • the conveying belt 16 may be omitted.
  • Each bag 25 is constrained by a fixed upper plate or grille 26 and side members 27.
  • a flexible plate 28 is fixed at 29 to the machine framework an dextends beneath the bag 25 above belt 16.
  • each bag 25 may span two steam chests 14.
  • Inflation of the bags 25 is adjustable to determine the load imposed on the belt, but as with the liquid-filled vessels, the bags will enable the plates 28 to follow any undulation in the belt 16 and board 10, 12 due to distortion of surfaces 15.
